最近可再生能源发电的扩散给人类带来了对抗全球气候变化的希望。然而，要获得这些可再生能源的全部好处，就需要能够以经济、安全和可持续的方式储存和分配产生的任何可再生能源。因此，钠离子电池（nib）因其丰富的元素、良好的电化学性能和环保特性而被吹捧为一种有吸引力的存储技术。此外，钠电池材料的新发展使采用不含稀土元素（如Li， Co, Ni）的高压高容量阴极成为可能，为低成本nib提供了途径，使其在能量密度上与锂电池相匹配，同时满足大规模电网储能的需求。在这篇文章中，我们讨论了一系列的电池化学成分，以及它们各自的电池特性，同时牢记电网存储的指标。讨论了有关材料和全电池成本、供应链和环境可持续性的问题，重点是需要从nib中消除几种元素（Li, Ni, Co）。讨论了未来的研究方向，以及克服电池安全性和可持续可回收性障碍的潜在策略。
The recent proliferation of renewable energy generation offers mankind hope, with regard to combatting global climate change. However, reaping the full benefits of these renewable energy sources requires the ability to store and distribute any renewable energy generated in a cost-effective, safe, and sustainable manner. As such, sodium-ion batteries (NIBs) have been touted as an attractive storage technology due to their elemental abundance, promising electrochemical performance and environmentally benign nature. Moreover, new developments in sodium battery materials have enabled the adoption of high-voltage and high-capacity cathodes free of rare earth elements such as Li, Co, Ni, offering pathways for low-cost NIBs that match their lithium counterparts in energy density while serving the needs for large-scale grid energy storage. In this essay, a range of battery chemistries are discussed alongside their respective battery properties while keeping metrics for grid storage in mind. Matters regarding materials and full cell cost, supply chain and environmental sustainability are discussed, with emphasis on the need to eliminate several elements (Li, Ni, Co) from NIBs. Future directions for research are also discussed, along with potential strategies to overcome obstacles in battery safety and sustainable recyclability.
